Introduction:
Microsoft 365 is a cybersecurity environment with no network to watch: there is no traffic to inspect and no endpoint to instrument — only the record of what accounts did. Detection here therefore rests entirely on behaviour, which is also why it catches the case where the credentials were genuine.
Vectra AI Cloud Detection and Response (CDR) for M365 is an advanced AI-powered solution designed to defend against malicious threats to applications and data in Microsoft 365.
Product Description:
Vectra AI CDR for M365 provides cloud attack detection and response, identifying and stopping unknown attackers hiding in the M365 SaaS environment. It applies Attack Signal Intelligence™ to activity inside the tenant, which is aimed at the early signs of a hybrid cloud compromise rather than at known indicators. Vectra AI has 12 references within the MITRE D3FEND framework, demonstrating its threat detection capabilities.
Customer Benefits:
Vectra AI CDR for M365 provides complete visibility and context, AI-driven detection and prioritization, and integrated investigations. It also offers shared responsibility for 24/7 protection, supporting analysts in jointly defending the customer’s M365 environment.
Target Audience:
Vectra AI CDR for M365 is designed for enterprises using Microsoft 365 that are looking for effective protection against malicious threats in their cloud environment.
